Unknown method on ResultObject

Error message

Unknown method on ResultObject: '{method}'

What it means

Catch-all arm of the Jinja method dispatch on ResultObject: only the 'keys' method is implemented (deliberately retained for dbt-external-table's stage_external_sources macro); any other method invocation raises this UnknownMethod error. Data access should go through the response/table/data attributes instead.

Solutions

1. Use attribute access (response, table, data) or the 'keys' method
2. Fix the method name in the template
3. Extend the match arm if a new accessor is required — but keep 'keys' for dbt-external-table compatibility

When it happens
